SeeburgCorporation, Chicago, 111., a corporation of 11- linois ApplicationOctober 11, 1943, Serial No. 505,776 21 Claims. (Cl. 177-353) Thisinvention relates to selectors for automatic phonographs in which one ormore recordings can be selected for playing seriatim.

One of the objects of the invention is to provide an improved selectorwhich is adapted to control the selection of any of a large number ofrecordings.

A further object of the invention is to provide an improved phonographselector arranged to be operated by a plurality of series of impulses,the numbers of the impulses in the two series determining the individualrecording selected.

Our improved selector is particularly adapted for use with a dialarranged to transmit a desired number of impulses. This dial may be ofconventional type and it may be located at any desired position remotefrom the phonograph.

While the specific embodiment of the invention hereinafter described isarranged for selecting any of one hundred recordings, this is a matterof convenience only, because the number of impulses-which the dial maybe arranged to transmit can be varied at will. Thus, instead ofemploying a dial capable of transmitting ten different series ofimpulses, we may arrange a dial to transmit twenty-six or any otherdesired number of impulses, depending upon the number of selectionswhich the phonograph is arranged to p ay.

It is to be noted that the invention is not intended to be limited to adial. Any other selector control which can be operated to transmit twoseries of impulses can be used with the present selector.

In selectors operating with two series of impulses, it has notheretofore beenpossible to use these impulses to transfer a selectormember to an individual position by movements in the same direction.Thus, if the selector is actuated to select recording No. 65, then inprevious phonograph selectors of this general type a selector arm islocated in the sixth row and at the fifth element of that row as aresult of the first series of six impulses and the second series of fiveimpulses.

One of the objects of the present invention is to provide an improvedselector in which both series of impulses move the same element step bystep in one direction. I

In the specific embodiment hereinafter described, I provide means formoving a single selector means first in large steps and then in smallsteps to correspond to tens and units. For this purpose we employe twoseparate mechanisms for stepping the tens and units.

to provide a new relation of the steppingmechanisms whereby themechanisms may be returned in convenient manner to zero positions.

Other objects and capabilities of the invention will appear from thefollowing description of preferred embodiments and the accompanyingdrawings in which:

Figure 1 is an elevational view, partly in section, through a selectorembodying my invention;

Fig. 2 is a sectional plane/thereof, the section being taken on the line2+2 of Fig. 1;

Fig. 3 is a diagrammatic perspective view of details involving the unitstepper;

Fig. 4 is a plan view of the tens stepper mechanism, this being asectional view taken on the line 4-4 of Fig. 1;

Fig. 5 is a wiring diagram.

Referring to the drawings, and particularly Figs. 1 to 5 thereof, ourimproved. selector comprises an arcuate series of selector elements 20slidably mounted ina stationary frame Al. Each selector element 20corresponds to an individual recording and the upward displacement of Va selector element 20 starts the motor 22 of the phonograph, with theresult that the recordchanging mechanism is put into operation and thatindividual record is played.

The record-selecting mechanism efiects the return of the displacedselector element 20 after a motor switch, in parallel with the switchelements associated with the selector elements 20, has been closed bythe record-changing mechanism.

In copending application Serial No. 342,419, filed June 26, 1940, byMarion R. Winkler, there is shown a plurality of displaceable selectorelements which operate and are controlled in the manner just described.In that application the selector elements were actuated from normalposition by individual solenoids. In the present application a singleelement'mechanically displaces the desired selector element 20.

Thus, the phonograph motor 22 may be energized from a secondary 23 of atransformer, one

side of which is grounded and the other is connected to the motor 22.The other side of the motor 22 is connected to an insulated ring 24.Each selector element 20 carries a resilient switch arm 25 which isadapted to engage the ring 24 One of the objects of the presentinvention is when the selector element is moved upwardly into selectingposition. It will be apparent from Fig. lthat when one or more selectorelements 20 are thus moved upwardly, the circuit of the motor :12 iscompleted and the motor goes into operaon. I

A' switch 26 is arranged in parallel relation to the switch elements 24and 26, the switch 26 being arranged to be momentarily opened at the.

nism of the phonograph so that the corresponding record is moved out forplaying. After the drive of the disk 21 terminates. a returning member26 is moved downwardly so as to return the arresting selector element.The motor 22 continues to operate since the switch 26 is closed untilthe record is played and the switch 26 is opened by the record-changingmechanism.

In .the mechanism illustrated, the disk 21 moves only in one direction,but our invention is not intended to be limited in this respect. Thus,the disk 21 may be arranged for oscillatory movements and it may beconnected for example to the reciprocating carriage shown in applicationSerial No. 416,140, filed October 23, 1941, by Marion R. Winkler. Thepresent invention is concerned primarily with means for displacing theselecting elements 20.

It will be understood that any desired number of the selector elements26 may be projected upwardly, in which case the phonograph goes intooperation to play the record corresponding to the first selector element26 engaged by the abutment 26. After thisrecord has been played, thedisk 21 resumes its movement and engages the next projected selectorelement 26 and so forth until all the corresponding records have beenplayed and all the ,projected selector elements have been returned toinitial position.

Means are provided for sesiliently holding the selector elements 26 intheir normal and projected positions. Thus the frame 2| may include twospaced plates 26 through which the selector elements 26 extend. Anannular coil teeth on the ratchet wheel 22. The ratchet wheel 22 ismounted for free rotation on a shaft 24 which is rotatably mounted in aframe 26 below the frame 2| and in axial alignment with the arcuateseries of selector elements 26.

A selector arm 26 is pivotally mounted on the upper side-of the ratchetwheel 22. The arm 26 is pivotally mounted on a frame 21 which is securedto the upper side of the ratchet wheel 22 so that the arm 26 extendsinagenerally radial or dimetrical relation to the ratchet wheel. Theframe 21 may comprise a slotted guide memberllaoastoretaintheselectorarmllinradialor diametric relation to the wheel22 while permitting the arm pivot.

26 to swing upwardly about its.

In alignment with the shaft 24 the arm 36 is provided with an upwardlydirected clevis member 26 which has a swivel connection to the armature46 of a relay 4|. The relay 4| is rigidly mounted on the frame 2| andsince the clevis member 29 is arranged in alignment with the shaft 24,it will readily be understood that the.

ratchet wheel 22, together with the arm 36, may rotate freely withreference to the solenoid 4|.

In each of its selecting positions the arm 26 is located beneath one ofthe selector elements 26 and consequently when the relay 4| isenergized, the arm 26 moves upwardly and projects the aligned selectorelement 26 upwardly with the result that the honograph is set inoperation in the manner previously described.

Above the ratchet wheel 32 a collar 46! is rigidly secured to the shaft34. The collar 4 carries a pin 4 which abuts against a pin 42 carried bythe rachet wheel 22. A grooved collar 42 is also rigidly mounted on theshaft 24. A coil spring 44 secured to the collar 42 and to the ratchetwheel 22 tends to keep the pin 42 in engagement with the pin 4| i whilepermitting the ratchet wheel 22-to be moved in the clockwise direction,as viewed in Fig. 2, to carry the pin 42 away from the pin 4| I.

An escapement wheel 46 is rigidly secured to the lower end of the shaft24. A long coil spring 46, anchored to the grooved collar 43, extendsaround a roller 41 mounted on the frame 26 a d extends downwardly to a'suitable point of anchorage, which is shown on the motor 46 carried atthe lower end of the frame 36. This spring is arranged so as to bias theshaft 24 in the clockwise direction as viewed in Fig. 2.

As will hereinafter be described, the motor 46 is arranged to drive theshaft 24 to an initial or normal position in which an abutment 49 on theescapement wheel 46 engages an abutment 62 on .the frame 26.

The escapement wheel 46 cooperates with an escapement 6| which isintegral with the armsture of a relay 62. The relay 62 is rigidlycarried by a vertical shaft 62 mounted on the frame 26 in alignment withthe shaft 24'. Also rigidly mounted on the shaft 62 is a contact disk 64which provides for the connections forthe may 62 and the switch 66associated with that relay.

The shaft 62 freely carries a gear 66 which is located between twofriction plates 61. A sprin 66 abuts against a collar 66 rigidly mountedon the shaft 62 and against apressure disk 66 located on the upper sideof the upper friction plate 51. The lower friction plate 61 bearsagainst a plate 6| rigidly mounted on the shaft 52. It will thus be seenthat the gear 66 is operatively connected to the shaft 62 by means of anoverload clutch which permits slippage of the gear 56 relative to theshaft 62 in the case of overload.

The gear is connected by gear reduction means to the drive pinion 62 ofthe motor 46. V

gear 62. The gear 66 meshes with a large gear 66 which is rigidlyconnected to a gear 16 in mesh with the gear 66. The gears 62, 64 and61, 66 are freely rotatable on a shaftdepending from the frameof themotor 46. The gears 66 and I6 are rigidly secured to another shaftmounted for free rotation on the frame of the motor 46.

The gear assembly 55, 88 is freely rotatable on the last-mentionedshaft.

The gear drive is arranged so that the shaft 53 is positively driven bythe motor 48 in the counter-clockwise direction as viewed in Fig. 2.

When the motor 48 is thus put into operation,

the relay 52 is driven in the counterclockwise direction as viewed fromabove in Fig. 2 and the escapement 5| carries the escapement wheel 45with it until the abutment 43 engages the abutment 50. As willhereinafter appear, the motor circuit is broken at about this time andany tendency of the motor to overrun is absorbed by the frictionmounting of the gear 55.

The teeth on the escapement wheel 45 have a'spacing corresponding to tenspacings of the selector elements or ten tooth spacings on the ratchetwheel 33. It is to be noted that at the beginning of a selectionoperation, the relay 52 may have any of a plurality of positions with 20respect to the escapement wheel 45. One position is shown in Fig. 4 butthe escapement 5| may be in engagement with any tooth on the escapementwheel 45. In other words, the escapement 5| may have at the beginning ofa selection operation its position in Fig. l or any other position oneor more tooth spaces from its position in Fig, 4.

The switch 55 mounted on the frame of the relay 52 is arranged to closemomentarily each time the relay 52 is energized, that is, each time atens impulse is received.

The unit-stepping relay I0 is mounted on the frame 35. The armature H ofthis relay has pivoted thereon an actuating arm or detent I2. The arm 12is held close to the back of the armature 1| by means of a. strap 13carried in spaced relation to the" armature H. The arm 12 projectsupwardly through an opening 14 in the relay frame to a position close tothe teeth of the ratchet-wheel 33.

Each time that the relay I0 is energized the arm or detent. 12 movesinto engagement with the ratchet wheel 33 and moves it one tooth spacein the clockwise direction as viewed in Fig. 2. The pivotal mounting ofthe arm 12 on the armature 1| permits the detent to follow the arcuatemovement of the ratchet wheel 33 during its engagement. a A holding dog15, pivotally mounted on the frame of the relay I0, is arranged toengage the teeth of the ratchet wheel 33 so as to hold the ratchet wheelagainst counterclockwise movement during reception of the unitsimpulses.

I Initially the holding dog 15 is latched out of engagement with theratchet wheel 33 by means of a locking lever 16. The lever 13 is biassedinto latching position by a spring 11. The dog 15 is biassed towards theratchet wheel 33 by a spring 18. I

The dog 15 is moved into latching position by a lever 13 biassed out ofengagement with the dog 15 by a spring 80. An arm 8|, rigidly secured tothe collar 43 and consequently to the shaft 34, is arranged to engagethe lever IS!v when the shaft 34 is in its normal position with theabutments 49 and 5B in engagement.

The arm 8|, in the initial or normal position of the selector, as shownin Fig. 2, engages an insulation member 82' so as to effect the closingof a switch 83 and the opening of switches 84 and 85. These switches areconstituted by levers mounted on the frame of the relay III.

'Switch 83 is biassed open and switches 84 and 85 are biassed closed.

The armature 'll carries an arm 88 which extends from the rear side ofthe armature and is provided with a bent end which extends behind a pin81 which projects downwardly from the latch 15. It will thus be seenthat when the first units impulse is received, that is, the firstimpulse which energizes the relay 10, the arm 88 moves the latch 16 intounlatching position so that the dog 15 enters into cooperativeengagement with the ratchet wheel 33 during the first units impulse.

Associated with the armature II is a switch 88 which closes momentarilyduring each units impulse. v 1

In order to facilitate understanding of the invention, a briefdescription of the operation of the mechanical parts thereof is nowgiven: The first series of impulses are switched so that they energizethe relay 52. the relay 52 the escapement 5| is actuated andconsequently the shaft- 34 is moved in the clockwise direction as viewedin Fig. 2 a number of tens steps correspondingto the number of impulsesreceived. In the specific embodiment disclosed in Figs. 1 to 5; the arm35 is located twenty-two steps away from the first of the series ofselector elements 20 regarded in the clockwise direction in Fig. 2.Incidentally, for this embodiment the dialling of the number 0 providestwo impulses, the dialling of the number 1 provides three impulses, andso forth.

Supposing the number 3" is. dialled first, then v the relay 52 receivesfive impulses and the arm 35 is brought to a position below thetwentyninth of the series of selector elements 2|] regarded in theclockwise direction on Fig. 2. This displacement of the arm 36 resultsfrom the displacement ofthe shaft 34 under the influence of the spring48, the escapement 5| being energized five times. The elements 19, 15and 16 were initially in their positions shown in Fig. 2. 0n the firstimpulse the arm- 8| moved away from the lever 19 and from the insulatingmember 82. Consequently, the switches .83, and 35 moved to the reversepositions from that shown in Fig. 2 on the first impulse. The holdingdog 15 remains latched out by its engagement with the latch member 15.

The second series of impulses is arranged to energize the relay 10, oncefor each impulse. The first units impulse moves the latch 15 tounlatching position so that the dog 15 engages the teeth to the rachetwheel 33. Each energization of the relay 10, moves the rachet wheel 33one tooth in the clockwise direction as viewed in Fig. 2. During thereception of the units impulses the shaft 34 remains stationary and therachet wheel 33 is moved against the tension of the spring 44 carryingthe pin 42 away from pin 4| l. 7

If the second impulse is caused by moving the dial to the 5 position,seven impulses are transmitted and the arm 36 is moved from thetwentyninth to the thirty-sixth selector element 20.

Since the first selector element corresponds to .to No. 35) upwardly.Thereafter the motor 48 is put into operation and it moves the shaft 34back to initial position with the stops 49 and 50 in engagement.

On each energization of At the time this engagement occurs. the arm iengages the piece of insulation 02 and opens the switch 00, whereuponthe motor ceases to be energized. At the same time, the arm 0| swingsthe lever into engagement with the dog 10 so that this dog isoperatively disengaged from the rachet wheel 00 and is latched outautomatically by the latch 10. The disengagement oi the dog from therachet wheel 00 enables the spring 00 to turn the rachet wheel I; backto initial position which is defined bythe engagement of the pin 02 withthe pin H I.

It is to be noted that when the motor 40 thus operates, it carries theescapement I in the counter-clockwise direction five steps from itsoriginal position shown in Fig. 4. During successive selections therachet ii is moved in counterclockwise direction a certain number oftens steps corresponding to the number of the tens impulses in theselection last made.

Referring now to Fig. 5, the manually operable dial 00 cooperates withthe switch 00 so that on the manual action of the dial the switch 00remains open and when the dial is released to resume normal position,the switch 90 is closed a number oi times, depending upon thedisplacement of the dial. One side oi the dial 00 is grounded, the otherbeing connected-through a limiting. resistor (suitably 10,000 ohms) tothe grid of a gas tube II. This tube may suitably be a 205i tube, thegrid of which is connected I is connected to one side of the relay 5!.The

other sides oi the relays 02 and 10 are connected to the high side ofthe secondary ll of the power transformer 00. The other side of thesecondary.

84 is grounded. The high side of the transformer 00 is connected to theplate of the tube Si by a by-pass condenser 00. switch 00 is connectedto the common pole of the two switches 0H and 02. One side 01 the switch[I is grounded, the other being connected to one side 01' the relay 00.The other side or the relay is connected to a source of 200 volts D. C.This source is also connected to one side oi the relay 91 and through alimiting resistor 00 (suitably 100 ohms) to one side of a normally openswitch 00 controlled by the relay 01. associated with the relay 91 is anormally closed switch I00. The common pole of the two switches 00and-i00is connected through a condenser III to ground. The other side ofthe switch I00 is connected to a relay I02 which controls the normallyopen switches I03 and I04.

Two sides of the switches I00 and I04 are connected together to the highside of the secondary I00 oi the transformer 05 and to normally openswitches I06 and I01 controlled by relay I00. The other side of theswitch I01 is connected to the motor 40, the other side of this motorbeing grounded. The other side oi the switch I00 is connected to theother side of the relay I00 and to the other side of the switch I04.

The other side of the.

Also

to the relay 0i, the other side of which is grounded. Relays 03 and 01are slow-release relays so that they may remain energized dur-- ing threception of decades impulses and units impulses, respectively.

The operation will now be amplified with reference to Fig. 5 and withreference to the previous description of the mechanical parts of theselector. Actuation oi the dial 00 results in the closing of the switch00 five times. Each time the switch is closed, the voltage of the gridof the tube 8i becomes substantially zero and the tube flashes. Thefirst flash of the tube supplies plate current from secondary 8|, relay10, and normally closed switch 00. After the first impulse switch 83 isopened and switches 04 and are closed, the first energization oi therelay 10 closes the switch 00 and completes the circuit of the relay 00so that switch 02 closes and switch 9 opens. Relay 93, being aslow-opening relay, maintains these switches in the conditions mentionedduring the reception of the tens impulses. The second'and subsequenttens impulses pass plate current from secondary 00 through relay 10,closed switch 82 and closed switch 84. The relay 10 thus receives fiveimpulses and the arm 30 is moved to a position beneath the twenty--ninth selector element 20 (No. 28). On the termination of the tensimpulses the relay 0! becomes deenergizecl, the switch 02 opens and theswitch I closes, switch 03 remains open and switches 04 and 80 remainclosed.

For the second or units impulses. the dial is operated with the aid ofthe opening corresponding to 5," and consequently the switch is closedseven times. The plate circuit is completed through closed switch 80,closed switch I, relay I2 and secondary 04. On the first units impulse,the relay 01 closes switch 00 and open switch I00. This conditionpersists during the reception of the units impulses and the condenser MIis charged at 200 volts D. C. Each unit impulse energizing the relay 10moves the ratchet wheel one tooth in the clockwise direction as viewedin Fig. 2, that is, a total of seven teeth, so that the arm 30 isbrought beneath the twenty-sixth selector element 20 (No. 35). At theend of the second series of impulses, relay 01 becomes deenergized,switch 00 opens, and switch I00 closes. The condenser IOI thendischarges throughthe relay I02, energizing this relay and closingswitches I00, I00. The closing oi the switch I00 completes a circuitfrom secondary I00 through relay II so that the arm 00 is moved upwardlyto project selector element 20 (No. 35) upward to selecting position.

The momentary closing oi the switch i00 energizes relay I00 through theclosed switch 00. The energization oi the relay I00closes switches I00and I01. The closing of the switch I01 completes the circuit of themotor 40 so that the same starts to operate to return the shaft 00towards.

its initial, position wherethe abutmcnts ll and I0 engage. The closingof the switch I00 maintains the relay I00 energized through the circuitI00, I00, I00 and closed switch 80.

When the motor 00 has driven the shaft 00 almost back of its normalposition, the arm II misses the piece oi insulation 02 and opens theswitch 00. At the same time the arm 0i turns the lever 10 in clockwisedirection as viewed in Fig. 2, moving the dog 10 clear oi the ratchetThe other side or the switch III is connected 75 wheel 00. This ratchetwheel is now rotated in counterciockwisedirection as viewed in Fig.2

by" the spring 44 until the pin 42 hits against the pin ll l.

The movement of the dog 15 by the pivoted lever I9 results in theautomatic latching out of the dog 15 as shown in Fig. 2 and the dog 15remains in this latched-out position until the first units .energizationof the next selection operation again energizes the relay 10.

It will be understood that any desired selector elements 20 and anydesired plurality thereof can be projected upwardly by a sequence ofdouble actuations of the dial 89.

It may here be remarked that if the No. is dialled twice, the arm 36 isadvanced twentytwo steps, so that the first of the selector elements 20(No. 00) is projected upwardly. It is preferred to have at least twoimpulses to prevent the selector from responding to accidental impulsesonthe line. Accidental impulses will ordinarily not have the timerelation necessary for maintaining the relay 93 or relay 91 energized.

No selection can be made by two accidental impulses. It requires twopairs of at least two impulses with the proper time relation to effectactuation of any selector element 20. It will of course be understoodthat we may use a greater number of fdead impulses. Thus we may arrangethe mechanism so that the dialling of 00 gives two series of three, fouror more impulses to bring the arm 36 into alignment with the firstselector element 20 (No. 00)

It will of course be understood that the dial 89 may be located at anysuitable position remote from the restof the mechanism herein described.The line connecting the switch 90 to the limiting resistor may be of anydesired length and this line is consequently shown broken in thedrawings.

Although the invention has been described in connection with specificdetails of a preferred embodiment thereof, it must be understood thatsuch details are not intended to be limitative of the invention exceptin so far as set forth in the accompanying claims.
